UV-1900: Perfect instrument for all analytical challenges
UV-Vis spectroscopy has never been so fast and easy
UV-Vis spectrophotometer UV-1900
The new UV-1900 spectrophotometer integrates a progressive double-beam optical system with Shimadzu’s patented Lo-Ray-Ligh® diffraction grating technology in a Czerny-Turner type monochromator. This technology ensures low stray light with a photometric repeatability previously unknown in its instrument class.
UV-1900 also guarantees maximum efficiency with the industry’s fastest level scan function (29,000 nm/min); it takes just three seconds to measure in all wavelength regions. Controlled using easy-to-handle color touchscreen or the new LabSolutions UV-Vis software, UV-1900 is perfect for optimizing laboratory workflow.

High technologies combine for unprecedented abilities
Known from high-end models, the Lo-Ray-Ligh® diffraction grating brings the lowest stray light level in its class (less than 0.5 % @ 198 nm) to the UV-1900. It ensures high photometric repeatability with high accuracy, offering one of the largest ranges of linearity (see figure 2).

The UV-1900’s optical system also shows the highest resolution in its class (1 nm) which guarantees maximum measurement accuracy as required by Pharmacopeia. Moreover, the new ultra-fast scan function enables users to perform accurate measurement with an amazing scan speed of 29,000 nm/ min. This reduces analysis time significantly and enables elucidation of fast chemical processes.
Perfect instrument for all analytical challenges
The color touchscreen (controlled by fingertip or included stylus) is accompanied by an intuitive program design. All typical programs (photometric, spectrum, quantitation, kinetics, time-course and biomethod for DNA or protein quantification) are accessible without the need for a PC. The on-board validation and security functions enable full support for Pharmacopoeia, GLP/GMP, FDA and other regulations. Moreover, the sample compartment accepts many common accessories such as the sipper unit, temperature control and the Specular Reflectance Measurement Attachment.
This qualifies the UV-1900 as the perfect standalone instrument for many application fields such as food, pharma or chemistry. The entire spectral range can be scanned in a matter of seconds. Whereas until now only the intensity at one significant wavelength could be observed for time-course measurements, the change of the entire absorption spectrum can now be investigated.

LabSolutions UV-Vis for advanced capabilities
With the aim of improving work efficiency by exploiting UV-1900 maximum capacities, the new LabSolutions UV-Vis Software is intended for frequent users of UV-Vis spectrophotometers in various applications.
The clear and simple program layout fits into the LabSolutions family (LabSolutions IR, LabSolutions RF). System and measurement configuration workflows are optimized by easy to follow windows and self-explanatory icons.

Different programs are accessible via the LabSolutions Manager. From the start, spectrum, quantitation, photometric and time-course are available. The new Spectra Evaluation Function makes quality control easier than ever with automatic judgement for the samples analyzed. Additional programs, e.g. color analysis, can also be added as options.
Multiple data sets can be exported easily with just a click to other formats such as batch text or Microsoft Excel. Moreover, LabSolutions UV-Vis supports the user with convenient functions such as real-time display of concentration data or automatic determination of optimal parameters for peak detection.

Compliance with ER/ES regulations is assured with the Shimadzu LabSolutions DB or CS platform. These tools provide a project management function suited to tasks and system operations. These functions enable equipment and user management, security policy and data processing to be set on a project by project basis, there-by improving the efficiency of data searches and management tasks.

The new UV-1900 defines a new standard for compact UV-Vis spectrometers. Lo-Ray-Ligh® diffraction grating technology in the double-beam instrument enables excellent photometric specifications while the color touchscreen and connection to LabSolutions UV-Vis provide an easy state-of-the-art workflow, both in standalone and PC controlled operation while still being fully compatible with UVProbe. Its broad range of measurement modes and compliance with international regulations open many application fields for this compact instrument.
